Problem D: 字符类的封装

Description

先来个简单习题，练练手吧！现在需要你来编写一个Character类，将char这一基本数据类型进行封装。该类中需要有如下成员函数：

1. 无参构造函数。

2. 构造函数Character(char)：用参数初始化数据成员。

3. void setCharacter(char)：重新设置字符值。

4. int getAsciiCode()：返回字符的ASII码。

5. char getCharacter()：返回字符值。

6. 析构函数。

Input

输入只有1行，包含一个合法的、可打印的字符。

Output

输出有好多行，请参考样例来编写相应的函数。

Sample Input

c

Sample Output

Default constructor is called!Character a is created!ch1 is c and its ASCII code is 99.ch2 is a and its ASCII code is 97.Character a is erased!Character c is erased!

HINT

Append Code

#include <iostream> using namespace std; class Character { private: char c; public: Character() { c = '0_0'; cout << "Default constructor is called!" << endl; } Character(char _c) { c = _c; cout << "Character "<< c <<" is created!" << endl; } char getCharacter() { return c; } int getAsciiCode() { return c; } void setCharacter(char _c) { c = _c; } ~Character() { cout << "Character " << c << " is erased!" << endl; } }; int main() { char ch; Character ch1, ch2('a'); cin>>ch; ch1.setCharacter(ch); cout<<"ch1 is "<<ch1.getCharacter()<<" and its ASCII code is "<<ch1.getAsciiCode()<<"."<<endl; cout<<"ch2 is "<<ch2.getCharacter()<<" and its ASCII code is "<<ch2.getAsciiCode()<<"."<<endl; return 0; }
